An area of low pressure currently showing up on water vapor satellite imagery over southwest Arizona will strengthen overnight and begin to lift northeast across New Mexico and the Texas panhandle bringing rain and snow to the panhandle region overnight and into tomorrow. Current surface observations are showing rain beginning to enter into far western and northern sections of the panhandle. As temperatures continue to fall, this precipitation will increase and change over to snow most likely around midnight. Snow will continue to develop and increase in coverage and intensity overnight and into tomorrow morning bringing a range from 1 to over 6+ inches of snow in portions of the Texas and Oklahoma panhandles by Tuesday evening. A few areas may encounter snow accumulations greater than 6 inches. In addition to the panhandle region, parts of western and central Oklahoma will also be under the gun for winter weather into tomorrow afternoon and evening. Driving is expected to become hazardous tonight and tomorrow over much of I-40 from the OKC area all the way into New Mexico. We encourage you to stay off the roads in these areas if you do not have to be out tonight and into tomorrow. We’ve got a few graphics below to outline the snowfall coverage and amounts based on the latest forecast model guidance.
The first graphic is courtesy of the NWS Amarillo.
The next graphic comes from the 12km NAM forecast model. As you can see, it pretty much maxes out at about 6 inches for most of the region with an isolated area of around 8 inches just outside of Amarillo. This graphic displays accumulations through Noon tomorrow.
The NWS in Amarillo has put together a special Winter Weather Center page where you can obtain the latest info with an easy link to report snow amounts in your area!
